Kim Kardashian

Kim, Kourtney, and Khloé wrote an autobiography entitled Kardashian Konfidential. The book was released in stores on November 23, 2010.
In December 2010, Kardashian filmed a music video for a song titled "Jam (Turn It Up)". The video was directed by Hype Williams; Kanye West makes a cameo in the video. Kardashian premiered the song during a New Year's Eve party at TAO Las Vegas on December 31, 2010. The song was produced by The-Dream and Tricky Stewart. Kardashian said that she was forced into doing the song by friends such as Ciara, Kanye West, and "Turn It Up" producer The-Dream. When asked if an album is in the works, Kardashian replied: "There's no album in the works or anything – just one song we did for Kourtney and Kim Take New York, and a video Hype Williams directed, half of the proceeds we're giving away to a cancer foundation, because The-Dream's and one of my parents passed away from cancer. It's just all having fun – with a good cause". Jim Farber, writing for the Daily News, called the song a "dead-brained piece of generic dance music, without a single distinguishing feature," and suggested that the single made Kardashian the "worst singer in the reality TV universe."
Kardashian's 2010 earnings were the highest among Hollywood-based reality stars, being estimated at $6 million.
